Strong surjectivity of maps from 2-complexes into the 2-sphere

Given a model 2-complex K(P) of a group presentation P, we associate to it an integer matrix Delta(P) and we prove that a cellular map f : K(P) -> S(2) is root free (is not strongly surjective) if and only if the diophantine linear system Delta(P) Y = (deg) over right arrow (f) has an integer solution, here (deg) over right arrow (f) is the so-called vector-degree of f

Tokamak magnetic field lines described by simple maps

The magnetic field line structure in a tokamak can be obtained by direct numerical integration of the field line equations. However, this is a lengthy procedure and the analysis of the solution may be very time-consuming. Otherwise we can use simple two-dimensional, area-preserving maps, obtained either by approximations of the magnetic field line equations, or from dynamical considerations. These maps can be quickly iterated, furnishing solutions that mirror the ones obtained from direct numerical integration, and which are useful when long-term studies of field line behavior are necessary (e.g. in diffusion calculations). In this work we focus on a set of simple tokamak maps for which these advantages are specially pronounced.

Equivariant Nielsen root theory for G-maps

Let X be a compact Hausdorff space, Y be a connected topological manifold, f : X -> Y be a map between closed manifolds and a is an element of Y. The vanishing of the Nielsen root number N(f; a) implies that f is homotopic to a root free map h, i.e., h similar to f and h(-1) (a) = empty set. In this paper, we prove an equivariant analog of this result for G-maps between G-spaces where G is a finite group. (C) 2010 Elsevier B.V. All rights reserved.

RH maps of bovine chromosomes 15 and 29: conservation of human chromosomes 11 and 5

Comparative mapping data on evolutionary conserved coding sequences and synteny maps between human and cattle are insufficient to define the extent and distribution of conserved segments between these two species, because the order of loci is often rearranged. A 5000-rad cattle whole-genome radiation hybrid (WG-RH) panel was constructed to provide high-resolution comparative maps and also to integrate linkage maps of microsatellites with evolutionary conserved genes and transcripts in a single ordered map. We used the WG-RH panel to construct radiation hybrid maps of bovine Chromosomes (Chrs) 15 and 29 (BTA15 and BTA29), integrating microsatellites from published linkage maps with selected genes. The comprehensive map of BTA15 consists of 24 markers. 13 of which were placed in the framework map. Eleven molecular markers compose the comprehensive map of BTA29. seven of which were placed in the framework map. We identified the homologous regions between bovine Chr 15 (BTA15) and human Chrs 5 and 11 (HSA5 and HSA11), as well as between BTA29 and HSA11, the present study demonstrates that WG-RH mapping is an efficient method for integrating multiple genetic maps into one map and for incorporating monomorphic Type I loci into ordered maps for comparison between species.

Caracterización y clasificación de la red hidrográfica de la cuenca del río Bobo, departamento de Nariño - Colombia

The object of this work was to make a morphometric characterization of the Bobo river watershed in the Nariño department in Colombia. A map was created from topographical maps (1:25.000 scale) using the drainage network and the limit of each 2nd order microbasin as database. Dimensional, drainage network and relief morphometric parameters were evaluated for a later hy-drological study. The drainage area was 224.97 km2, having a 71.31 km perimeter. The Bobo river watershed is considered to be 6th order and has 176 2nd order drainage channels, 34 3rd order drainage channels, 9 4th order drainage channels and 3 5th order drainage channels. Average drainage density is 3.71km/km2, reflecting its high density, having strong, dissected geological formation. The area has a typical Andean land-use pattern, having native wooded vegetation, traditional transitory potato and vegetable growing predominating.

On the existence of G-equivariant maps

Let G be a compact Lie group. Let X, Y be free G-spaces. In this paper, by using the numerical index i (X; R), under cohomological conditions on the spaces X and Y, we consider the question of the existence of G-equivariant maps f: X -> Y.

The mutation causing the black-and-tan pigmentation phenotype of Mangalitza pigs maps to the porcine ASIP locus but does not affect its coding sequence

The gene for agouti signaling protein (ASIP) is centrally involved in the expression of coat color traits in animals. The Mangalitza pig breed is characterized by a black-and-tan phenotype with black dorsal pigmentation and yellow or white ventral pigmentation. We investigated a Mangalitza x Piétrain cross and observed a coat color segregation pattern in the F2 generation that can be explained by virtue of two alleles at the MC1R locus and two alleles at the ASIP locus. Complete linkage of the black-and-tan phenotype to microsatellite alleles at the ASIP locus on SSC 17q21 was observed. Corroborated by the knowledge of similar mouse coat color mutants, it seems therefore conceivable that the black-and-tan pigmentation of Mangalitza pigs is caused by an ASIP allele a(t), which is recessive to the wild-type allele A. Toward positional cloning of the a(t) mutation, a 200-kb genomic BAC/PAC contig of this chromosomal region has been constructed and subsequently sequenced. Full-length ASIP cDNAs obtained by RACE differed in their 5' untranslated regions, whereas they shared a common open reading frame. Comparative sequencing of all ASIP exons and ASIP cDNAs between Mangalitza and Piétrain pigs did not reveal any differences associated with the coat color phenotype. Relative qRT-PCR analyses showed different dorsoventral skin expression intensities of the five ASIP transcripts in black-and-tan Mangalitza. The a(t) mutation is therefore probably a regulatory ASIP mutation that alters its dorsoventral expression pattern.

The bovine dilated cardiomyopathy locus maps to a 1.0-Mb interval on chromosome 18

Cardiomyopathies are myocardial diseases that lead to cardiac dysfunction, heart failure, arrhythmia, and sudden death. In human medicine, cardiomyopathies frequently warrant heart transplantation in children and adults. Bovine dilated cardiomyopathy (BDCMP) is a heart muscle disorder that has been observed during the last 30 years in cattle of Holstein-Friesian origin. In Switzerland BDCMP affects Swiss Fleckvieh and Red Holstein breeds. BDCMP is characterized by a cardiac enlargement with ventricular remodeling and chamber dilatation. The common symptoms in affected animals are subacute subcutaneous edema, congestion of the jugular veins, and tachycardia with gallop rhythm. A cardiomegaly with dilatation and hypertrophy of all heart chambers, myocardial degeneration, and fibrosis are typical postmortem findings. It was shown that all BDCMP cases reported worldwide traced back to a red factor-carrying Holstein-Friesian bull, ABC Reflection Sovereign. An autosomal recessive mode of inheritance was proposed for BDCMP. Recently, the disease locus was mapped to a 6.7-Mb interval MSBDCMP06-BMS2785 on bovine Chr 18 (BTA18). In the present study the BDCMP locus was fine mapped by using a combined strategy of homozygosity mapping and association study. A BAC contig of 2.9 Mb encompassing the crucial interval was constructed to establish the correct marker order on BTA18. We show that the disease locus is located in a gene-rich interval of 1.0 Mb and is flanked by the microsatellite markers DIK3006 and MSBDCMP51.

Arachnomelia in Brown Swiss cattle maps to chromosome 5

Arachnomelia in Brown Swiss cattle is a monogenic autosomal recessive inherited congenital disorder of the skeletal system giving affected calves a spidery look (OMIA ID 000059). Over a period of 20 years 15 cases were sampled in the Swiss and Italian Brown cattle population. Pedigree data revealed that all affected individuals trace back to a single acknowledged carrier founder sire. A genome scan using 240 microsatellites spanning the 29 bovine autosomes showed homozygosity at three adjacent microsatellite markers on bovine Chr 5 in all cases. Linkage analysis confirmed the localization of the arachnomelia mutation in the region of the marker ETH10. Fine-mapping and haplotype analysis using a total of 34 markers in this region refined the critical region of the arachnomelia locus to a 7.19-Mb interval on bovine Chr 5. The disease-associated IBD haplotype was shared by 36 proven carrier animals and allows marker-assisted selection. As the corresponding human and mouse chromosome segments do not contain any clear functional candidate genes for this disorder, the mutation causing arachnomelia in the Brown Swiss cattle might help to identify an unknown gene in bone development.

Cartografías de la ciudad. Representación y estilización lingüística en mapas mentales de Buenos Aires

Desde un enfoque constructivista del espacio urbano como producto social, en el presente artículo presentamos algunos aspectos teóricos y metodológicos para el análisis de las representaciones geosociales y la identidad urbana para luego investigar a partir de una selección de mapas mentales la imagen espacial que los hablantes expresan a través de las variedades lingüísticas que distinguen, estilizan y ubican en su cartografía mental de la ciudad. Se trata de un primer acercamiento a un corpus recopilado en 2013, que permite observar, por un lado, que la percepción del espacio urbano está basada en la fuerte identificación de los porteños con los barrios de la ciudad y, por otro lado, que existe en el imaginario colectivo una dicotomía norte-sur estilizada que se refleja tanto en lo social, lo espacial y lo lingüístico.

Plan de manejo de la costa de Río Negro : observatorio del ecosistema litoral y monitoreo de la biodiversidad

La Provincia de Río Negro, a través de su Constitución y de leyes específicas, adhiere “a los principios que sustentan el desarrollo sustentable de conformidad con la Carta de Naciones Unidas." En la costa marítima de Río Negro existen poblaciones relativamente densas y en aumento básicamente por la inmigración en busca de nuevos horizontes laborales. Los conflictos ambientales que se presentan son comunes a otras zonas costeras: contaminación de las aguas costeras por insuficiente o falta de servicios de tratamiento de aguas residuales, modificación, para desarrollo urbano, industrial y comercial, de hábitats críticos para el sostenimiento de pesquerías, vida silvestre, desarrollo de infraestructura costera inapropiada o mal diseñada que favorece procesos erosivos acelerados y/o interrumpen procesos ecológicos básicos, ocupación espacial desordenada que impide el acceso público a playas y otros terrenos públicos, manejo inapropiado de desechos sólidos, incumplimiento de la legislación en la zona costera; generación de conflictos intersectoriales, desarrollo desordenado de infraestructura con altos costos socioeconómicos, crecimiento de la frontera agropecuaria, deterioro de los suelos (sobrepastoreo, desertificación), introducción de especies exóticas, etc. En Río Negro se han relevado, aunque a diferente escala y muchas veces en forma discontinua, la mayor parte de los ambientes costeros considerados de mayor interés desde el punto de vista ecológico y/o productivo. Ejemplo de productos de estos estudios son las Areas Naturales Protegidas de Punta Bermeja, Caleta de Loros, Bahía de San Antonio, Complejo Islote Lobos y Puerto Lobos, así como la Reserva Pesquera Golfo San Matías. Sin embargo, la información se halla dispersa, por lo que la mayor parte de las veces no se puede contar con un panorama actualizado y globalizador que permita la toma de decisión en forma ágil y un real manejo de las especies y/o de su ambiente. Por ello se considera necesario g enerar un Plan de Manejo de la Costa Marítima de Río Negro, esto es, una clasificación del territorio de acuerdo a su grado de sensibilidad ecológica, expresado en unidades cartográficas ambientales, y estableciendo pautas de manejo para las mismas. Se optó por un Sistema de Inventario y Planificación de Recursos, adaptado a un método de Planificación Participativa en el que se involucra en forma directa, a través de encuentros y talleres, a los diferentes estamentos provinciales, municipales, centros de investigación, organizaciones no gubernamentales ambientalistas, organizaciones intermedias, especialistas. Para la Evaluación de los Elementos e identificación de Zonas de Mayor Sensibilidad Ecológica se utilizó un Método de Evaluación de Riesgos que permite cartografiar grado de Amenazas, Vulnerabilidad y Riesgo.
